Polish Noodle Casserole

Place cooked and drained noodles in a buttered 1 quart casserole dish. Mix sour cream, cottage cheese, minced onion, salt, powdered mustard, and white ground pepper. Mix the above with the noodles in the casserole dish. Bake in a preheated 350 F. oven for 25 minutes. (The noodles on top should begin to brown.) To be a bit more fancy, when the 25 minutes is over, pull the casserole out of the oven, smear it with a bit of butter, and allow it to cook another 5 to 10 minutes. To be even more fancy, sprinkle some Parmesan cheese on top of the butter before putting the casserole back into the oven.
